Description

Air cooling tubes condenser condensate down-comer

Technical field：

The utility model is related to a kind of pipeline, relates in particular to a kind of air cooling tubes condenser condensate down-comer.

Background technology：

Domestic thermal power plant Air-cooled Unit condenser working medium circulation is that the condensate that will cool down turbine discharge formation leads to Cross down-comer and be back to header tank, supply boiler is used.But, due to air cooling tubes condenser condensate down-comer vertical riser cloth Put, condensate whereabouts drop is big, energy release is excessively concentrated, pipeline internal medium flowing instability, on the one hand, can cause down-comer Vibration is violent, noise is big, and on the other hand, the drop that condensate falls in down-comer is larger, can act on down-comer and catchment Connecting bend between case, causes down-comer and elbow junction, elbow and header tank junction weld cracking, influence unit peace Full economical operation.At present, down-comer is generally fixed using suspension and support, and down-comer is solved in the method that outside installs clip etc. additional and shaken Dynamic problem, the method can only temporarily reduce decline tube vibration, noise be reduced not substantially, and after long-play, and vibration adds Play, original reinforces suspension and support and clip easily ftractures, it is impossible to tackle the problem at its root.

Utility model content：

The purpose of this utility model is that offer is a kind of can make the air cooling tubes condenser of condensate steady flow in pipeline Condensate down-comer.

The utility model is implemented by following technical scheme：Air cooling tubes condenser condensate down-comer, it includes two end pipes, some Separator tube and some connecting tubes, are coaxially fixed with some separator tubes and some connections between two end pipes Pipe, the separator tube and the connecting tube are disposed between two end pipes；It is provided with inside the every end pipe Cloth member, the equal cloth member includes two pieces of annular oriffices and some dividing plates, two pieces of outers of the annular oriffice and the corresponding end Inside pipe wall is welded and fixed, and some dividing plates are welded between two pieces of corresponding annular oriffices；In the every buffering Pipe inner upper and be respectively arranged below with one piece of regular polygon orifice plate, each drift angle of the regular polygon orifice plate with it is corresponding The buffering inside pipe wall welding.

Further, it is welded between described each drift angle of regular polygon orifice plate and the corresponding buffering inside pipe wall and is added Strong plate.

Further, the drift angle interlaced arrangement of the regular polygon orifice plate in the every separator tube.

Further, the regular polygon orifice plate is equilateral triangle orifice plate, described in two in the every separator tube Equilateral triangle orifice plate journey Central Symmetry.

Advantage of the present utility model：The condensate flowing that equal cloth member can be flowed through is uniform, prevents condensate from concentrating landing, and Each regular polygon orifice plate can play buffering, scattered effect to the condensation current for declining, and condensation current is declined step by step, reduce The drop that condensate falls；Equal cloth member is combined with regular polygon orifice plate can be reduced condensate and concentrate what whereabouts caused to tube wall to rush Hit, make the steady flow in pipeline of condensation current, so as to reach the purpose for reducing pipe vibration and reducing noise.

Specific embodiment：

As shown in Figures 1 to 5, air cooling tubes condenser condensate down-comer, it includes two end pipes 1, some separator tubes 2 and some Connecting tube 3, is coaxially fixed with some separator tubes 2 and some connecting tubes 3, separator tube 2 and connecting tube 3 between two butt pipes 1 It is disposed between two butt pipes 1；Using weldering between separator tube 2 and adjacent connecting tube 3, between connecting tube 3 and end pipe 1 The mode for connecing is fixed；Equal cloth member 4 is provided with inside every butt pipe 1, equal cloth member 4 includes two pieces of annular oriffices 4.1 and some dividing plates 4.2, two pieces of outers of annular oriffice 4.1 are welded and fixed with the inwall of corresponding end pipe 1, between two pieces of corresponding annular oriffices 4.1 It is welded with some dividing plates 4.2；The every inner upper of separator tube 2 and one piece of regular polygon orifice plate 5 is being respectively arranged below with, it is just polygon Each drift angle of shape orifice plate 5 is welded with the inwall of corresponding separator tube 2, slow with corresponding in each drift angle of regular polygon orifice plate 5 Reinforcing plate 6 is welded between the inwall of washing pipe 2, reinforcing plate 6 can be such that regular polygon orifice plate 5 more stablizes with the connection of separator tube 2, jail Gu, it is to avoid the weld seam between regular polygon orifice plate 5 and separator tube 2 occurs because of the phenomenon that water impact is broken；Every separator tube 2 The drift angle interlaced arrangement of interior regular polygon orifice plate 5, drift angle interlaced arrangement can further make current uniform, prevent from being released in capability set Put, and then strengthen vibrationproof, the effect of noise reduction；Regular polygon orifice plate 5 is equilateral triangle orifice plate, two in every separator tube 2 Equilateral triangle orifice plate journey Central Symmetry, compared with the regular polygon orifice plate 5 of other shapes, equilateral triangle orifice plate and separator tube Gap between 2 inwalls is maximum, it is ensured that the flow velocity that condensate declines.

In air cooling tubes condenser running, after condensate enters the end pipe 1 of top, the annular oriffice of top is first struck 4.1, and enter between corresponding two annular oriffices 4.1 through the eyelet and centre bore on upper annular orifice plate 4.1, and at each In the presence of dividing plate 4.2, current are divided into multiply thread, and after through the eyelet on lower endless orifice plate 4.1 and centre bore stream Go out；The condensate flowed out by top end pipe 1 flow through successively eyelet and regular polygon orifice plate 5 on each regular polygon orifice plate 5 with Gap between the inwall of separator tube 2, it is final import below end pipe 1 in, and by after the equal cloth member 4 in lower section end pipe 1 through even Connect elbow and flow into header tank；In above process, the condensate flowing that equal cloth member 4 can be flowed through is uniform, prevents condensate from concentrating Landing, and each regular polygon orifice plate 5 can play buffering, scattered effect to the condensation current for declining, and make condensation current step by step Decline, reduce the drop that condensate falls；Equal cloth member 4 is combined with regular polygon orifice plate 5 can reduce condensate concentration whereabouts to pipe The impact that wall is caused, makes the steady flow in pipeline of condensation current, so as to reach the purpose for reducing pipe vibration and reducing noise.

Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model Protection domain within.
